        take any  position,  tax or otherwise,  or make any filing  inconsistent

        greater than the Closing Date Net Book Value; or

            (b)  increased  to the extent the  Reference  Net Book Value is less
        than the  Closing  Date Net Book Value.
        Section 2.6 Final  Adjustments.  Final  adjustments to the Cash Purchase
Price will be determined as follows:

            (a) Buyer will prepare,  in good faith and in accordance with GAAP a
        consolidated  pro forma  balance sheet of the Business as of the Closing
        Date (the "Closing Financial  Statements"),  together with a report (the
        "Final Adjustments Report"),  based on the Closing Financial Statements,
        setting forth in reasonable  detail  Buyer's  calculation of the Closing
        Date  Net  Book  Value.   Buyer  shall  deliver  the  Closing  Financial
        Statements and Final Adjustments  Report to Sellers within 90 days after
        the Closing Date. In preparing the Closing Financial  Statements,  Buyer
        will  use the  following  practices.  The  closing  date  balance  sheet
        ("Closing  Date  Balance  Sheet")  will  be  prepared  in a  proper  and
        consistent  basis in  accordance  with  the  standards,  principles  and
        practices  utilized  in the  Balance  Sheet.  No  change  in  accounting
        principles used in preparing the Balance Sheet will be made in preparing
        the closing date balance sheet of the Sellers. The Sellers' consolidated
        closing date balance  sheet  account will be prepared on a basis that is
        consistent  with the Balance  Sheet  including,  but not limited to, the
        following:

                (i) For  purpose of valuing  Inventory  and  long-term  contract
            balances: Inventory will be valued on a consistent basis between the
            Closing Date Balance Sheet and the Balance Sheet.  Consistency would
            include the margins  utilized in the  calculation  of the  Inventory
            included  in the PIR  sheets as of June 30,  2001,  which  shall not
            change for the  Closing  Balance  Sheet  calculation  based upon any
            judgmental  changes  regarding  profitability of a job (i.e.  margin
            change) with no activity since June 30, 2001; for any contracts that
            are  materially  closed out  between  June 30,  2001 and the Closing
            Balance  Sheet,  changes  will be made only to comply  with GAAP and
            Percentage-of-Completion  accounting rules; the Inventory at Closing
            will include the actual  overhead  rate rather than the applied 150%
            overhead  rate  calculated  by the  system;  all  contract  margins,
            including  Estimate-at-Completion (EAC) margins, shall be calculated
            using the actual  overhead  rate rather than the applied  150% rate;
            and all  stock/inventory  with no value (i.e.  capitalized labor and
            overhead on closed  jobs) will be valued at zero in the Closing Date
            Balance Sheet.
<page>
                (ii) For purposes of calculating  depreciation and amortization:
            the bases and rates of  depreciation  and  amortization  used in the
            Balance  Sheet  will be  consistently  applied at the  Closing  Date
            Balance Sheet. No changes to the depreciation and amortization rates
            as well as the accumulated balances,  including retroactive changes,
            will be  allowed  in the  interim  period  between  the two  balance
            sheets.

                (iii) For the purposes of  calculating  provisions and accruals:
            the Closing Balance Sheet shall only reflect decreases in provisions
            and accruals since the Balance Sheet that result from utilization of
            the provision or accrual (i.e.  payment of services,  use over time,
            etc.) and adjustments to the actual rates incurred up to the Closing
            Date, both according to GAAP rules.  Any Changes in judgment between
            the two period will not be  reflective  in the Closing  Date Balance
            Sheet.

            (b) Within 30 days after receipt of the Closing Financial Statements
        and the Final  Adjustments  Report,  Sellers  shall  notify Buyer of its
        objections to the Final Adjustments  Report, if any. Any amount which is
        not in dispute shall,  within five business days after the expiration of
        the review  period,  be paid by wire transfer in  immediately  available
        funds.  Any  payment to be made by Sellers  shall be first paid from the
        Escrow Funds.

            (c) The parties  shall in good faith  attempt to resolve any dispute
        with  respect  to  the  Final  Adjustments  Report  and/or  the  Closing
        Financial  Statements,  such  resolution of the dispute to be conclusive
        and binding  upon the  parties.  If the  parties do not reach  agreement
        resolving the dispute within 15 days after notice is given by Sellers to
        Buyer pursuant to clause (b) above, the parties shall submit the dispute
        to  a  nationally  recognized   independent   accounting  firm  mutually
        agreeable  to the  parties,  which  firm  shall not have had a  material
        relationship with either Buyer or Sellers or their respective Affiliates
        within the two years  preceding the  appointment  (the  "Arbiter"),  for
        resolution.  If  the  parties  cannot  agree  on  the  selection  of the
        independent accounting firm to act as Arbiter, the parties shall request
        the American  Arbitration  Association  to appoint such a firm, and such
        appointment shall be conclusive and binding upon the parties.  Promptly,
        but no later than 20 days after its  acceptance  of its  appointment  as
        Arbiter,  the Arbiter shall determine,  based solely on presentations by
        Buyer and Sellers,  and not by independent  review, only those issues in
        dispute and shall  render a report as to the  dispute and the  resulting
        change  in  computations  in the Final  Adjustments  Report  and/or  the
        Closing  Financial  Statements,  if any,  which shall be conclusive  and
        binding upon the parties.  In resolving any disputed  item,  the Arbiter
        shall  use GAAP in the  manner  described  in  Section  2.6(a)  above in
        determining  balances  in the  balance  sheet,  and  shall not take into
        account any changes in circumstance or events  occurring after the close
        of business on the Closing  Date.  The fees,  costs and  expenses of the
        Arbiter (i) shall be borne by Buyer in the proportion that the aggregate
        dollar   amount  of  such   disputed   items  so   submitted   that  are
<page>
        unsuccessfully  disputed by Buyer (as finally determined by the Arbiter)
        bears to the  aggregate  dollar  amount of such items so  submitted  and
        (ii) shall  be borne by Sellers  in the  proportion  that the  aggregate
        dollar amount of such disputed items so submitted that are  successfully
        disputed by Buyer (as finally  determined  by the Arbiter)  bears to the
        aggregate dollar amount of such items so submitted.  Whether any dispute
        is resolved by agreement among the parties or by the Arbiter, changes to
        the Final Adjustments Report and the Closing Financial  Statements shall
        be made hereunder  only for items as to which Buyer has taken  exception
        as provided  herein.  Buyer and Sellers each shall make available to the
        other  (upon the  request of the other)  their  respective  work  papers
        generated  in  connection  with the  preparation  or review of the Final
        Adjustments  Report and the Closing  Financial  Statements.  The payment
        required after determination of all disputed amounts will be made by the
        responsible  party  therefor  to the  other  party by wire  transfer  of
        immediately  available  funds within three business days after the final
        determination is made.

        Section 2.7 Earnout Payment As more  specifically  described  below, the
Sellers  may earn  additional  consideration  ("Earnout")  in the form of annual
earnout  payments  (each an "Earnout  Payment")  depending on the ability of the
Buyer and its  subsidiaries,  divisions and affiliates to achieve  organic Gross
Profit  Growth from the Unit,  as defined  below,  during the five Earnout Years
(the  "Earnout  Period")  following  the Closing  Date with respect to the gross
profits base set forth below.

            A base Earnout of $12,500,000  will be allocated  equally across the
            five-year Earnout Period, i.e. $2,500,000 per year.

            The Earnout Payment for each Earnout Year shall be equal to:

            (Actual Gross Profit minus Gross Profit Base) X $2,500,000
            Projected Gross Profit Growth

            For  purposes  of this  calculation,  the  following  values for the
            applicable Projected Gross Profit Growth and Gross Profit Base shall
            be used:

                                            Projected
                                       Gross Profit Growth    Gross Profit Base

               2002                       $5,360,000             $14,500,000
               2003                       $8,117,000             $15,000,000
               2004                       $10,585,000            $16,000,000
               2005                       $13,572,000            $17,000,000
               2006                       $17,658,000            $17,500,000

            The maximum  potential  earnout is $4,000,000 per year (unless there
        is an acceleration of remaining Earnout Payments due to a sale of all or
        part  of  the  Unit),  and  the  total  maximum   potential  earnout  of
        $20,000,000 for the five-year  Earnout  Period.  Buyer shall pay Earnout
        Payments  to the  Sellers  within  sixty  (60)  days  of the end of each
        Earnout Year according to the payment  instructions  provided by Sellers
        unless  such  payments  are  accelerated  as provided  for  herein.  The
        attached Exhibit D shows an example of an Earnout calculation.

            For purposes of this Section, the following definitions apply:

        (a) The term  "Actual  Gross  Profit"  shall  mean,  for the  applicable
            period,  as determined in accordance  with GAAP,  the gross revenues
            attributable to the sale, lease, license, sublicense or distribution
            or other  commercial use of products and services and related assets
            that comprise the Unit, as defined below, less (1) sales commissions
            payable to third  parties,  (2)  unreimbursed  freight and  shipping
            charges,  (3) refunds for returns,  and (4) the direct labor, direct
            material  costs and overhead  costs in respect of such  products and
            services,  provided  that if the  manufacturing  for the Business is
            relocated  after the Closing Date to any  facility  other than those
            used by Sellers prior to the Closing,  direct labor  expenses  shall
            not exceed the percent of direct labor and material  costs set forth
            on  Schedule  2.7 for the  purposes of the  Earnout  Payments.  If a
            product or service of the Unit is combined  with another  product or
            service of Buyer or its affiliates,  divisions or subsidiaries, then
            gross revenue  attributable to the products and services of the Unit
            shall  be equal  to the  total  gross  revenue  attributable  to the
            combination  product,  multiplied  by a fraction,  the  numerator of
            which is the then current  stand-alone price (without  discounts and
            not lower  than  reasonable  market  value)  for such  products  and
            services of the Unit, and the  denominator of which is the aggregate
            price of the  combination  products or services,  where the non-Unit
            products  or  services  included  in  the  combination  products  or
            services  are valued at current  stand alone prices  (without  price
            increases attributable to the proposed combination).

        (b) The term  "Earnout  Year"  means  those  twelve  (12) month  periods
            commencing  on  January  1,  2002  and on  subsequent  anniversaries
            thereof.

        (c) The  term  "Unit"  means  the  business  unit(s)  of CW  Flight,  CW
            Corporation, and any of their subsidiaries, divisions and affiliates
            that  (i)  utilize  the  Purchased  Assets  and  all   enhancements,
            modifications,  derivatives  or  developments  thereto;  and/or (ii)
            provide  products  and  services in  connection  with  programs  and
            businesses listed on Schedule 2.7 (collectively, the "Unit").

            From and after the Closing  Date,  Buyer agrees to (i)  operate,  or
        cause to be  operated,  the  Business in good faith and in the  ordinary
        course through December 31, 2006 to the end that the Buyer will not take
        any  action,  and  will  refrain  from  taking  any  action  that  could
        reasonably  be expected to  artificially  lower or otherwise  affect the
        annual Earnout  Payment,  (ii) provide  Sellers'  Representative  with a
        segregated  accounting  of the Unit to  enable  Sellers  to  review  the
        Earnout  calculation;  (iii)  report  all items of revenue  and  expense
        relating  to the Unit in the  periods in which they are  incurred,  (iv)
        provide the Chairman of LDS or his designee with an income statement for
        each  Earnout  Year  within 90 days of such year end,  (v)  provide  the
        Chairman of LDS or his designee with a calculation of the annual Earnout
        Payment within 90 days of the end of each Earnout Year, (vi) provide the
        Chairman  of LDS or his  designee  with a  quarterly  balance  sheet and
        income  statement for the Unit, and (vii) provide the Chairman of LDS or
        his designee with a certification by the Chief Financial  Officer of the
        Buyer that the items in the preceding  clauses  (iv),  (v) and (vi) were
        prepared in accordance with GAAP.

            Buyer agrees to a minimum  yearly  aggregate  budget for  marketing,
        general and  administration and research and development for the Unit of
        US$  4,760,000  for the first  Earnout  Year and 6.8% of the prior  year
        actual  annual  sales  revenues of the Unit for all  subsequent  Earnout
        Years,   excluding  returned  products   (collectively,   the  "Resource
        Allocation"). Buyer's compliance with this requirement shall be measured
        in the aggregate, rather than by individual cost category, provided that
        the  allocation  of spending  within the aggregate  Resource  Allocation
        shall reflect  reasonable  business  judgments about how to increase the
        value of the Unit.  If the Resource  Allocations  are not devoted to the
        Unit in any  Earnout  Year,  Buyer  shall  pay the  Seller  the  maximum
        potential  Earnout  Payment of $4,000,000 for that Earnout Year. The sum
        of this payment plus the Earnout Payment  actually made for that Earnout
        Year shall not exceed the maximum  potential  Earnout Payment,  absent a
        sale or transfer of assets from the Unit, of $4,000,000 per year.

            If CW  Corporation  undergoes a Change in Control (as defined below)
        prior to  December  31,  2006,  then the  obligations  relating  to this
        Earnout shall be assumed by the acquiring entity. In the event that such
        acquiring  entity fails to make any required Earnout Payments within ten
        (10)  business  days of the date  such  Earnout  Payments  are due,  the
        Earnout for all  subsequent  Earnout Years (and portions  thereof) shall
        become immediately due and payable without further demand or notice, or,
        for disputed  Earnout  Payments,  after pursing to a final  decision the
        arbitration  procedures  provided for in Section 13.12. For the purposes
        of this  Section  2.7,  "Change of Control"  shall be defined as (i) the
        consolidation of CW Corporation with or acquisition of CW Corporation by
        another entity in a merger,  stock purchase,  or other reorganization in
        which the  holders of the  outstanding  voting  stock of CW  Corporation
        immediately preceding the consummation of such event shall,  immediately
        following  such  event,  hold,  as a group,  less than a majority of the
        voting securities of the surviving or successor entity; or (ii) the sale
        of all or substantially all of CW Corporation's assets.

            If  Buyer  or its  affiliates,  subsidiaries  or  divisions  sell or
        otherwise  transfer any of the assets,  securities or any portion of the
        business of the Unit (the  "Transferred  Assets") to a third party prior
        to December 31,  2006,  other than a sale of such assets in the ordinary
        course  of  business  or  as a  result  of a  Change  of  Control  of CW
        Corporation,  then the present value (as calculated with a discount rate
        equal  to the  annual  treasury  bill  rate at the  time of the  sale or
        transfer of Transferred Assets) of the maximum potential Earnout for all
        subsequent  Earnout  Years  (prorated  for partial  years)  shall become
        immediately due and payable with respect to the Transferred Assets, such
        payment to be calculated as follows.  The maximum  potential Earnout for
        all  subsequent  Earnout  Years  (prorated  for partial  years) shall be
        multiplied  by a fraction,  the  numerator  of which shall be the Actual
        Gross Profit  attributable to the Transferred  Assets between January 1,
        2002  and  the end of the  most  recent  fiscal  quarter  preceding  the
        transfer,  and the denominator of which shall be the Actual Gross Profit
        of the Unit  between  January  1,  2002  and the end of the most  recent
        fiscal quarter  preceding the transfer (the  "Percentage").  The Earnout
        shall  continue  to apply to the  balance  of the Unit  with the  yearly
        maximum potential  Earnout,  the Projected Gross Profit Growth,  and the
        Gross  Profit  Base  all  reduced  by the  Percentage  for  purposes  of
        calculating subsequent Earnout Payments.

            Buyer and its subsidiaries, divisions and affiliates will permit LDS
        and its  representatives to have access to all books and records and the
        right to review all Buyer  activities  necessary to evaluate the Earnout
        calculation,  the Resource Allocation for each Earnout Year, the earnout
        obligations  relating  to the SPA,  and  Buyer's  purchasing  activities
        involving  purchase  of the  assets  specified  in  Schedule  2.3 (g) or
        similar assets during the Earnout Period.

            If  LDS   disputes   the  Buyer's   determination   of  any  Earnout
        calculation,  it shall  notify  Buyer in  writing (a  "Dispute  Notice")
        within thirty (30) days of its receipt of the Buyer's determination.  In
        the event of such a dispute,  LDS and Buyer  shall  first use their best
        efforts to resolve the dispute. If the dispute cannot be resolved within
        ten  (10)  days,  it  shall  be  submitted,  to  an  independent  public
        accounting firm on which the Parties  mutually agree (the  "Accountant")
        for  resolution.  Within 30 days after  submission  of the dispute,  the
        Accountant  shall  determine the Earnout  calculation in accordance with
        this  Agreement.  The  Accountant's  determination  shall be  final  and
        binding upon the  Parties,  and the Buyer shall  immediately  pay to the
        Seller  any  additional  amount  of  Earnout  due  as a  result  of  the
        Accountant's determination. The fees and expenses of Accountant shall be
        shared equally by LDS and Buyer.

                                  ARTICLE III.

                    REPRESENTATIONS AND WARRANTIES OF SELLERS

        Sellers represent and warrant to Buyer that:

        Section 3.1 Organization.  LDS is a limited  liability  corporation duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
Commonwealth of Massachusetts.  LDS Acquisition is a corporation duly organized,
validly  existing and in good  standing  under the laws of the  Commonwealth  of
Massachusetts.  Vista is a corporation  duly organized,  validly existing and in

requisite corporate power and authority to own, lease and operate the properties
of the Business, including the Purchased Assets, and to carry on the Business in
the places where such  properties  are now owned,  leased or operated,  and such
Business is now conducted.  Each of the Sellers is duly qualified to do business
as a foreign corporation and is in good standing under the laws of each state or
other  jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the  activities  conducted by it,  requires such
qualification except where failure to be so qualified would not, individually or
in the aggregate, have a Material Adverse Effect.

        Section 3.2  Authorization;  Enforceability.  Sellers have all requisite
corporate power and authority to enter into each Acquisition  Agreement to which
it is a party and to perform its obligations hereunder and thereunder.  All acts
required to be taken by Sellers to authorize  the  execution and delivery of the
Acquisition  Agreements to which they are a party,  and the  consummation of the
transactions  contemplated  herein and  therein,  have been taken,  and no other

corporate  proceedings  on the part of Sellers are  necessary to authorize  such
execution,  delivery and performance.  This Agreement has been duly executed and
delivered by Sellers and  constitutes a legal,  valid and binding  obligation of
Sellers, enforceable against Sellers in accordance with its terms, except to the
extent such  enforceability  may be limited by applicable  bankruptcy  and other
laws affecting  creditors'  rights,  or by general  equitable  principles.  Each
Acquisition  Agreement to which  Sellers are a party will be, as of the Closing,
duly  executed and delivered by Sellers and will  constitute a legal,  valid and
binding obligation of Sellers in accordance with its terms, except to the extent
such  enforceability  may be limited  by  applicable  bankruptcy  and other laws
affecting creditors' rights, or by general equitable  principles.  The execution
and  performance of each  Acquisition  Agreement,  and the  compliance  with the
provisions  hereof and thereof by Sellers,  will not conflict  with,  violate or
result in the  breach  of any of the  terms,  conditions  or  provisions  of the
respective  charter or by-laws of Sellers,  as the case may be, or any judgment,
order, injunction, decree, law, regulation or ruling of any Governmental Body to
which  Sellers,  the Purchased  Assets  and/or the Business are subject,  except
where the same would not impede  Sellers'  ability  to perform  its  obligations
under the Acquisition  Agreements or have a Material  Adverse Effect.  Except as
indicated  on  Schedule 3.2  hereto,  the  execution  and  performance  of  each
Acquisition Agreement, and the compliance with the provisions hereof and thereof
by Sellers,  will not result in any breach of any of the terms or conditions of,
or constitute a default under, any license,  indenture,  mortgage,  agreement or
other  instrument  to which any of  Sellers  is a party or by which it is bound,
except where such breach or default would not impede Sellers' ability to perform
their  obligations  under the Acquisition  Agreements or have a Material Adverse
Effect.

        Section  3.3  Capitalization.   The  authorized  capital  stock  of  LDS
Acquisition consists of 200,000 shares of common stock, $.01 par value, of which

are issued  and  outstanding.  All of such  issued  and  outstanding  shares are
validly issued,  fully paid and  nonassessable  and will be transferred to Buyer
free and  clear of any  liens  or  encumbrances.  There  are no  outstanding  or
authorized  options,  warrants or similar agreements to which any of the Sellers
are a party  providing  for the  issuance or  acquisition  of any of the capital
stock of LDS Acquisition or Vista.

        Section  3.4  Financial   Statements.   Exhibit A  hereto  contains  the
unaudited  Balance  Sheet of the  Business  as of June 30,  2001 and the related

are in  accordance  with the books and records of each of the Sellers,  (ii) are
accurate  in all  material  respects,  (iii)  fairly  present,  in all  material
respects,  the financial condition and the results of operations of the Business
as at and for the twelve month  period  ending  December  31, 2000,  for the six

31, 2001, and (iv) have  been prepared in accordance  with GAAP. To the Sellers'
Knowledge,  the Sellers do not have any debt,  liability  or  obligation  of any
nature, whether accrued,  absolute,  contingent or otherwise,  whether due or to
become due,  related to the Business,  that is not reflected or reserved against
in the Financial  Statements or set forth in the Exhibits and Schedules  hereto,
except for those  which are not  required  by GAAP to be  included  in a balance
sheet.

        Section 3.5  Government  Approvals.  Except for the filing  requirements
under the HSR Act and as set forth on Schedule  3.5 hereto,  the Sellers are not
required  to submit  any  notice,  report or other  filing  with,  or obtain any

consent,  approval or waiver from, any Governmental  Body in connection with its
execution,  delivery  or  performance  of  the  Acquisition  Agreements,  or the
consummation  of the  transactions  contemplated  herein or therein,  except for
notice,  consent and approval requirements  associated with Contracts in which a
Government Body is a party, and except where the failure to make such submission
or obtain such consent,  approval or waiver,  would not have a Material  Adverse
Effect and would not impede Sellers'  ability to perform its  obligations  under
the Acquisition Agreements.

        Section  3.6 Fixed  Assets;  Properties;  Liens.  Sellers  own or lease,
subject  only to the terms of the  Contracts  and the matters  permitted  by the
following sentence,  all the properties and assets (whether real,  personal,  or

properties and assets included in the Purchased Assets are free and clear of all
liens and encumbrances.

        Section 3.7  Condition  of Assets.  Except as set forth in Schedule  3.7
hereto,  to the Seller's  knowledge,  the  buildings,  plants,  structures,  and
equipment  included in the Purchased  Assets are  structurally  sound and are in
reasonable operating condition, ordinary wear and tear excepted, and the Sellers
are in  material  compliance  with their  maintenance  obligations  under  their
respective real property leases.

        Section 3.8 Taxes.  Each of Sellers and their  Affiliates  have filed or
caused to be filed on a timely basis all Tax returns  that are or were  required
to be  filed  by  them  or  with  respect  to  it  as a  member  of a  group  of
corporations.  All of Sellers' and Affiliates'  Taxes required to have been paid
on or prior to the date hereof have been paid in full. All Taxes that Sellers or
the Affiliates is or was required to withhold or collect have been duly withheld
or  collected  and,  to the  extent  required,  have  been  paid  to the  proper
Governmental Body or other entity or Person. Except as set forth in Schedule 3.8
hereto, there are no assessments against Sellers with respect to Taxes that have
been issued and are  outstanding.  Except as set forth on Schedule 3.8, there is
no Tax  deficiency  outstanding  or assessed or proposed  against either Sellers
that is not  reflected  as a  liability  on the Balance  Sheet nor have  Sellers
executed any  agreements or waivers  extending any statute of  limitations on or
extending the period for the assessment or collection of any Tax.

        Section 3.9 Compensation.  Sellers have previously  delivered to Buyer a

third party of the  existence  of any  liability,  obligation,  contract,  other
commitment  or state of facts  referred to in this Section  12.1,  except that a

third party of the  existence  of any  liability,  obligation,  contract,  other
commitment  or state of facts  referred to in this Section  12.2,  except that a
failure to provide such prompt notice shall not be a defense against a claim for
indemnity unless Sellers can demonstrate that they were materially prejudiced by
the  failure to provide  such  notice.  Buyer  shall be  entitled to control the
contest,  defense,  settlement or compromise  of any such claim  (including  the
engagement  of counsel in  connection  therewith),  at its own cost and expense,

either  party  pursuant  to Sections  12.1(i)  and 12.2(i)  above shall not take

arbitrator, the arbitrator shall be determined in accordance with the applicable
rules of the American Arbitration Association.

decision of the  arbitrator  shall be final and binding.  The  arbitrator  shall
divide all costs in conducting the  arbitration in the final award in accordance
with what is just and  equitable  under the  circumstances.  Except as otherwise
herein  provided,  each  Party  shall bear the  burden of its own  counsel  fees
incurred in connection with the arbitration proceedings under this Agreement.

confidential business information and no disclosure of such information shall be
made by either Party or the arbitrator  without the prior written consent of the
Party furnishing such information in connection with the arbitration proceeding.
